Description
Technical field
The present invention relates to a kind of motor more particularly to the higher motors of rotating ratio, if revolving speed is 100,000 revs/min ~ 150,000
Rev/min.
Background technique
Hair dryer, bladeless fan, the aspiration of negative pressure device, inflator pump, motor used in hand-held high-speed sander tool, at present
Usually brushless single phase motor, axially position are fixed with glue.
Brushless single phase electric efficiency is low, starting torque is small；Axially position is only fixed with glue, and glue is fixed, and there are two types of wind
Danger:Dispensing is more, may rolling bearing is viscous dead；Bearing is not firm, there is the danger to fall off.
In order to improve electric efficiency, eddy-current loss is reduced, this motor uses three-phase direct-current brushless motor, can bring make an uproar therewith
The big problem of sound, the purpose of the invention is to provide a kind of ultrahigh rotating speed and the small motor of noise.
Summary of the invention
In order to solve the problems, such as that in the prior art, the present invention provides a kind of ultrahigh rotating speed motors comprising motor 101, axis
Core 102, wave washer 103, axle sleeve 104, casing 105, fan blade 106, magnet ring 107, fixed frame 108, first bearing 109 and second
Bearing 110.
This motor uses three-phase direct-current brushless motor, reduces eddy-current loss to the greatest extent, and using three slots, two pole, three-phase motor is than single
Phase brush DC reliability starts reliability, and operation stability is high.
Because revolving speed is at 100,000 revs/min ~ 150,000 revs/min, in its natural state, high-speed cruising is very big to make an uproar bearing
Sound passes to bearing 2 by axle sleeve, there has also been pre- for bearing 2 by adding wave washer to do precompression to bearing 1 in bearing chamber
Pressure, in this way noise caused by the vibration of elimination bearing clearance.
Air duct and casing integration, are both used as casing, while being also the fixed frame of rotor, and fixed frame is axially fixed as bearing
Position electric machine support, saves space, makes structure more compact.
Fixed frame is solved perfectly and is in the market fixed with glue as bearing axially position before bearing chamber plus behind seam allowance
Hidden danger.
For general small brshless DC motor using gap structure between 0.2mm-0.4mm, the high revolving speed fever of this motor is tighter
Weight, while high voltage is easy reverse induction potential and causes to demagnetize, so the design strong magnetic of high brands of sintered Nd-Fe-B, larger to rectify
Stupid power and high temperature resistant, while increasing magnetic gap and using between 0.6mm-0.8mm, air gap flux density is reduced, high revolving speed is suitble to, and
And counter electromotive force and high temperature demagnetization are reduced, while reducing magnetic hysteresis torsion, while meeting performance requirement again.
The design of fan blade uniqueness lines, one is high-precision is needed, is done because machining, can leave machining lines
At smooth, but expensive, using machine direction lines with it is distinguished and admirable consistent, guarantee the flow-disturbing of fan, increase air inlet and the outlet
Efficiency, while greatly reducing processing cost.
The beneficial effects of the present invention are:
Compared with traditional electric motor mounting structure, such electric machine structure can be reduced the sound of high-speed cruising bear vibration；It is unique
Wind lines design on fan leaf, greatly reduces wind noise；Have many advantages, such as it is compact-sized, be easily installed, structure it is reliable；Gu
Frame is determined as the axially position of bearing while being used as electric machine support, greatly facilitates compact-sized and installation convenience.
